Description
ここで、I(glass)とは、非晶質ガラス(主成分はSiO2 )のX線回析のピーク強度を示し、I(Al2 O3 )とは、アルミナのX線回析のピーク強度を示す。
(焼成温度の実験)
本実施例においては、グリーンシート11a〜11dとして低温焼成セラミックス(LTCC:日本電気真空硝子株式会社製GCS71)を用いた。この低温焼成セラミックスでは、メーカー推奨焼成温度が量産用連続炉約870℃〜約900℃に設定されている。
図3は、積層セラミック基板10のX線回折(XRD)のスペクトルの一例を示す図である。図3の縦軸は強度を示し、横軸は回折角度2θ(deg)を示す。
次に、本実施例において、上記低温焼成セラミックスを用いて焼成温度をそれぞれ800℃、820℃、840℃、860℃、880℃および900℃に変化させて焼成を行った。
次に、焼成温度と短絡不良発生率との関係を検証すべく、実験用の炉で焼成温度を変化させて積層セラミック基板(サイズ6.7mm×5.0mm)からなる720個のアンテナスイッチモジュールを作製した。
次に、結晶化度と短絡不良発生率との関係を検証すべく、上記焼成温度を変化させて作製したアンテナスイッチモジュールの結晶化度を測定した。
次に、焼成温度と積層セラミック基板の焼結状態を示す焼結密度および結晶化度との関係を検証した。
次に、結晶化度が12%以下の積層セラミック基板10内の銀濃度と短絡不良率との関係について検証を行った。
